Abstract
Background: Ventilatory function and aerobic capacity each decline by {u223C}40%, with aging leading to ventilatory limitation ,dyspnea, exercise intolerance, which affected by performance of upper and lower limbs, so it is important in the elderly to use aerobic training to improve ventilatory function, by training upper limbs as well as lower limbs which not investigated previously. Aim of the study: To compare between the impact of upper versus lower limbs training on ventilatory function in elderly men. Methods: Eligible 40 elderly men their age ranged from (60-65) years old, body mass index (BMI) ranged from 25to34.9 kg /m2 participants were recruited from the outpatient clinic of faculty of physical therapy, Cairo University, Egypt.Patients were divided into two groups equal in number; the group (A) performed upper limbs training by arm ergometer, while the group (B) performed lower limbs training by cycle ergometer for three times per a week for 12 weeks. Ventilatory function included (Forced expiratory volume in the first second (FEV1), forced vital capacity (FVC), and FEV1/FVC ratio, peak expiratory flow rate(PEFR), and peak expiratory flow25-75%(PEF25-75%) were evaluated pre and post intervention for 12 weeks (36 sessions). Results: after 12 weeks of intervention, both groups demonstrated significant increase of FEV1, FVC, and PEFR (p< 0.05)in group A and group B respectively (23.56%,22.96%,29.36%) and (27.75%,25.37%,73.49%) by contrast there was no significant difference was observed in the mean of FEV1/FVC ratio and PEF25-75% between pre and post-intervention (p>0.05) in both groups A and B respectively(1.05%, 5.51%) and (9.07%, 13.39%)
